An examination of the spatial and temporal variability of seawater pCO2 within the Canadian Arctic Archipelago and Baffin Bay during the summer and fall seasons
The distribution of the partial pressure of surface water CO2 (pCO2sw) was measured throughout the Canadian Arctic Archipelago and Baffin Bay during the summer and fall. Throughout these two seasons, values ranged from 110 μatm and 436 μatm, demonstrating the high level of variability in pCO2sw acro...
